BUR-ROLL FOR LOOlVI-TEMPLES.

Specification'of Letters Patent.

Patented Dec. 16, 1919.

Application filed February 15, 1916. Serial No. 78,389.

To all whom it may concern:

Be it known that I, SrMnoN SoHooN J ACK- soN, a subject of Great Britain, residing at Readville, Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Bur- Rolls for Loom-Temples,'of which the following is a specification, reference being had therein to the accompanying drawings.

The invention comprises improvements in loom-temple bur-rolls of the type in which the teeth are integral with the body of the roll. One object of the invention is to effect an economy in the manufacture of a bur-roll of the said type. Another, is to give to a burroll of such type the advantage of a spiral alinement of the teeth thereof. A third object is to provide a roll having a novel combination of toothed and untoothed spiral projecting cloth-engaging and holding portions.

An embodiment of the invention is shown in the drawings, in which latter,

Figure 1 is a plan view of a temple of ordinary character having a bur-roll containing the said embodiment, the cap of the temple-head being broken away so as to show the roll more clearly.

Fig. 2 is a view of the bur-roll of Fig. 1 showing it separately and on a relatively enlarged scale.

Fig. 3 is an end view of the said roll.

Having reference to the drawings,

The bur-roll 1 is mounted in any approved manner in conjunction with the pod 2 and cap 3 of the temple.

The roll itself is composed of suitable metal. In carying my invention into effect, the body of the roll is grooved spirally by making a continuous spiral angular out 1 in the periphery thereof, thereby forming a sharp-edged continuous spiral rib 1 having its outer surface inclined toward one end of the roll, and preferably having its other surface slightly undercut as shown in Fig. 2.

The roll-body then is grooved longitudinally by making a series of equilateral V-shaped grooves 1 lengthwise thereof, these grooves cutting across or intersecting the successive turns of the spiral rib. Thereby I produce inclined sharp pointed pyramidal teeth 1 1, etc, the points of which all face toward one end of the roll. The longitudinal grooves do not extend the entire length of the roll-body, the roll being formed with one or more toothed sections and one or more sections of untoothed spiral sharp-edged rib. Figs. 1 and 3 show the roll toothed throughout the outer half of its length and furnished with untoothed spiral rib throughout its inner half. The toothed section takes the adjacent to that engaged by the toothed sec tion, although its action in connection with the cloth is less positive than that of the toothed section. lVith the teeth formed upon only the outer portion of the length of the roll, the penetrating, etc, action of the teeth is confined to the selvage-portion of the cloth, and the untoothed spirally ribbed inner portion of the roll serves as a rest or backing for the cloth.

The spiral grooving enables the cutting to be performed throughout the entire length of the roll by continuous spiral cutting, and gives both the toothed portion of the roll and the untoothed rib portion thereof the desirable advantage in operation that is due to the spiral disposition of the teeth and of the untoothed rib.

In case the roll-body is made of steel it is properly hardened after being cut.

I claim as my invention:

1. A loom-temple bur-roll having a continuous spiral line of inclined sharp-pointed pyramidal teeth integral with the body of the roll, and an adjoining continuous untoothed sharp-edged spiral rib which assists the toothed section in stretching and holding the web.

2. A loom-temple bur-roll having the outer portion of its'length furnished with a continuous spiral line of inclined sharppointed pyramidal teeth integral with the body of the roll, and the inner portion of its length furnished with a continuous untoothed outwardly inclined s iral rib.

In testimony whereof I a X my signature in presence of two witnesses.

SIMEON SCHOON JACKSON.
